Note 1.
| In
case of Hot rolled steel as base metal, the values in the table above adapts to
the thickness 1.6mm or more. |
|
2.
|
The values in the table above
represent the internal space of bend, expressed by the number of sheets of same
thickness. |
|
3.
|
The bending test shall be done
by bending a test specimen by 180º at a right angle to
the rolling direction. The outside of the bend shall be free
from exfoliation of the coating and from cracking and breaking
of base metal. This dose not apply to those parts of the specimen
that are within 7mm of either edge. |
